Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Naziritor chelynoides faces significant pressure from habitat degradation due to agricultural expansion and urban development within its limited range in the Western Ghats. Dam construction and water diversion projects have altered natural flow regimes in the streams where this species occurs. Collection for the aquarium trade poses an additional threat, as these distinctive freshwater fish are sought after by collectors.
